Abstract: PROBLEM TO BE SOLVED: To construct a bridge fall preventing structure in a short time by fitting a reinforcement member to the outer wall surface side of an abutment parapet formed on each of right and left abutments to form a fixing part, and disposing a PC cable through a bridge girder between both fixing parts. SOLUTION: A PC cable 6a passing a bridge girder 3 is fitted to a fixing part 10 formed on both sides of an outer wall of an abutment parapet 1a of right and left abutments 1A, 1B to construct a fall preventing structure E safely and in a short time without any influence on the passing vehicle under the bridge. The end of the PC cable 6a is provided with a bridge girder movement allowing means 20 formed by a rubber buffer member, a bearing plate, a spring member and a nut, whereby when the right and left abutments 1a, 1b are relatively varied due to a large earthquake, working force is applied to the PC cable 6a to support the bridge girder by the PC cable 6a. Thus, fall-down of the brige girder 3 which is the worst situation can be prevented.

Title: Focused position detector
Inventor: OKI MASAHIKO
IPC: G03B13/36
Filed: 1988-03-22
Abstract: PURPOSE:To execute real time processing, while simplifying an electrical processing circuit by executing a focused position decision, based on an output of an AND circuit, which is outputted, based on AND of an output based on OR of first and second transition detecting parts, and a fall detecting part of an output of a second comparator. CONSTITUTION:A line sensor 3 is placed in the longitudinal direction of a gap 10, and a part of an image corresponding to a gap part of a sample 1 is formed. An accumulated charge which is accumulated in this line sensor 3 is transferred successively as an image signal to a focused position detecting circuit 12. When an image signal generating optical system 2 is in a focused state against the sample 1, the image of the gap part of the sample 1 is formed distinctly in the line sensor 3, therefore, the image signal fetched by a series of transfer charges goes to a square wave-like detecting signal W which rises and falls quickly. In such a way, since a focused position can be detected, a real time processing can be executed, while simplifying an electrical processing circuit.
